I just get right to it.I been playing with Yafaray today and finally getting the chances of using it (For Linux 32-bit )Feels a whole new program for me to play with (First time using Yafaray)

I got a little suggestion, I was trying to find an option to turn off the Mipmaps filter in Textures tab but couldn't find it..Looks like Yafaray doesn't have that thing (Yet) or maybe i can't find it.

It is possible to add a Filter option? Like the one in Blender Internals and Cycles, there's a feature to make the textures not blurry and stay sharp.

This feature will be available in the upcoming YafaRay-E v1.1.0. However, if you want to use this feature now, you can make the changes manually yourself to your version to the python code in the exporter, just add the lines as indicated in the link above.
